Week 7: Key principles that are use to secure TCP/IP.




Fundamentally, TC/IP are not meant to be secure. This protocol does a lot, but it is not secure. Fortunately, there is room to implement to secure the protocol. Here are the five principles that are used to secure TC/IP: encryption, integrity, nonrepudiation, authentication, and authorization.

·       Encryption is the process of scrambling the data in which if it gets intercepted, they wouldn’t be able to read the data.

·       Integrity is the process of making sure the same data is received as originally sent.

·       Nonrepudiation is the process of holding people accountable in case they change the data through taking a log or other source for verification.

·       Authentication is the processing of verifying the identity of a person that is accessing the data and to verify to make sure the person is who they say they are.

·       Authorization is what an authenticated person has access to when it comes to the data.

Although not all layers of TCP/IP have the level of security, some layers uses one of this principle to make the protocol secure.

Week1: Introduction and Cloud Computing

Hello everyone, my name is Santosh Pradhan, and I am currently pursuing an undergraduate degree in information technology at Bellevue University. Prior to pursuing my degree, I had no prior experience, except for the basic troubleshooting that everyone learns. So far, I have learned a great deal about networking, basic information technology, and some cybersecurity concepts. Although most of the courses have covered virtualization and cloud computing to some extent, none of them have provided full details. I am excited to learn about cloud computing and its governance.  As the semester progresses, I will update the blog on a weekly basis and share my experiences with you.

Week 12: Tools for Monitoring Network and Blog Wrap-up

There are various tools to monitor a network; monitoring a network can help detect issues, be aware of the problems, or make sure the network does not have any anomaly in the network. Here are some of the tools that can help to monitor the network: ·        Packet Sniffers – a software tool that tracks and collects internet packets. The packets that are collected will be stored in a file called a capture file.  Usually, the packet sniffer software also comes with a packet analyzer to analyze the packets that were captured. ·        Protocol Analyzer – this is a program that analyzes the packets that packet sniffers capture. A good program can let the network administrator filter information based on their needs. One of the well-known software is Wireshark. ·         Packet Flow Monitoring – this tool tracks traffic and packet flow between devices. This helps to track the volume and ...

Week 3: Migration to the Cloud

Image
  This week, we learned about the various decision-making processes involved in migrating to the cloud. The book talks about five major phases of the migration process: Assess, Plan, Migrate, Validate, and Manage . While assessing and before initiating the migration process, it is essential to establish a baseline of the network, operating system, and other key performance indicators. It is essential to minimize the impact of downtime and maximize network bandwidth availability during the migration. After the planning process is done, there are various ways to execute it; the common migration processes are P2V, V2V, V2P & P2P. Amazon also provides a migration truck to make the process. The book also discusses deploying the migration and validating it to ensure that it is working through various types of testing, including functional testing, performance testing, load testing, and others.
